Extracting a Library Member
You can use LIB to create an object (.obj) file that contains a copy of a member of an existing library. To extract a copy of a member, use the following syntax:
LIB library /EXTRACT:member /OUT:objectfile
This command creates an .obj file called objectfile that contains a copy of a member of a library. The member name is case sensitive. You can extract only one member in a single command. The /OUT option is required; there is no default output name. If a file called objectfile already exists in the specified directory (or the current directory, if no directory is specified with objectfile), the extracted objectfile replaces the existing file.
